A usability study of dynamic geometry software's interfaces

The use of information technology such as dynamic geometry software in mathematics teaching has become more popular and essential. There are several benefits of using this software. In spite of the benefits, they have some difficulties in terms of usability, so users have some problems while using them in learning mathematics. The purpose of this study is to investigate the usefulness of these software interfaces. For this purpose, firstly, we selected two dynamic geometry software. One of them is GeoGebra and the other one is Geometer’ Sketchpad. After selecting, 6 tasks designated using this software. In usability test, the participants tried to do task. While doing the tasks, in order to analyze the process, the participants were observed and their eye movements were recorded with eye tracker system. Then their opinions about software asked. Finally all data were analyzed, and discussed
